Pandemic - What's Happened?

Pneumonia of unknown eteology was declared a public health emergency on the thirtieth of january 20 20. Many countries dealt with it quite seriously and used every capacity they had hand to limit the spread, while others did not. And i think the characteristics of this pirus were such that it could spread undetected. It could spread amongst people who were either had very limited symptoms and ease, or no symptoms at all. But it didn't it didn't have to be this bad. The big question right now for me is what changes are we going to make now? How do we use this horrific situation of this pendemic that we've all lived through because it will happen
